EYE-CUP.

Specification of Letters Patent.

Patented Nov. 18, 1913.

Application filed December 21, 1912. Serial No. 738,064.

To all whom it may concern:

Be it known that I, W. ERNEST PETERS, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Eye-Cups; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to eye-cups and has for an object to provide eye-cups carried upon a structure one part of which is an expansible air-ball and the other part of the structure being adapted to assist the proper application of the cups to the eyes.

A further object of the invention is to provide a tubular member constructed of somewhat flexible material having an expansible air-ball communicating with the tubular member with one branch located adjacent the ball and the other branch removed at a distance from the ball corresponding to the usual pupillary interval so constructed that the cup adjacent the ball is carried by comparatively inflexible material while the cup remote from the ball is carried by comparatively flexible material to permit its positioning.

With these and other objects in view the invention comprises certain novel constructions, combinations and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings: Figure 1 is a sectional view of the device. Fig. 2 is a view of the device in side elevation. Fig. 3 is a top plan view of one of the cups.

Like characters of reference designate corresponding parts throughout the several views.

The present invention embodies the use of a tubular member 10 constructed of material of such a thickness as to be comparatively rigid in its operation. Associated with the tubular member at one side is an expansible air-ball 11 with a cup 12 carried upon such tubular member. At the end of the tubular member oppositethe air-ball 11 the tubular member is reduced in thickness as indicated at 13 whereby the branch 14 is of greater flexibility than the remaining portion of the structure. The branch 14 carries a cup 15 similar to the cup 12. The object of the semi-rigidity of the tubular member 10 is that the operator grasping the air-ball 11 is enabled to position the cup 12 upon the eye by the hand holding the ball while the flexibility of the branch 14 is provided to permit the proper positioning of the other cup upon the other eye by the other hand of the operator. If the entire structure were made flexible to permit all parts to be easily flexed the eye-cup 12 would not be held properly in position simply by the force applied to the ball 11, whereas if the entire structure were made of the same semi-rigidity the cup 15 could not be easily and conveniently positioned.

The cups themselves are constructed with the usual concavities 16 with a plurality of ducts 17 communicating with the main duct 18, which latter passes through the nipple which is inserted within the ends of the tubular members 10 and 14.

I claim:

1. The combination with a U-shaped tubular member, one leg of which presents greater flexibility than the other member, of an airball communicating with the tubular member at the side possessing the greater rigidity, and eye-cups inserted into the ends of the tubular member.

2. The combination of a U-shaped tubular member, one extremity of which possesses greater flexibility than the remainder of the structure, an expansible air-ball located upon the side of the U possessing the less flexibility and communicating with the tu bular member and eye-cups inserted in the extremities of the U-shaped member.

3. In an eye-cup structure, a U-shaped tubular member constructed of elastic material. one extremity of which is thinner than the remainder of the structure, and an expansible air-ball located at the side of the U constructed of the thicker material and forming communication with the interior of such tubular member.

4. The combination with a U-shaped tunear the edge of said hemispherical portion bular member, of an air ball communicating and approximately tangential thereto. 10 with said tubular member, eye-cups inserted In testimony whereof I affix my signature in the ends of the tubular members, said eyein presence of two witnesses.
